This study aims to investigate the effects of defocus, sample thickness, accelerating voltage and aperture size on high resolution transmission electron microscopy (HRTEM) images of β-Si3N4 . This is done by employing the multislice method, which requires β-Si3N4 supercell to be constructed. Then, e...
